1.3 Central Processing Unit (CPU) This motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™ 2 Quad / Core™2 Exreme / Core™2 Duo / Pentium® dual-core / Celeron® dual-core / Celeron ® processors. Ensure that all power cables are unplugged before installing the CPU. • Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/transit-related. • Keep the cap after installing the motherboard. ASUS will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the LGA775 socket. • The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap. This motherboard supports Intel® Hyper-Threading Technology and Enhanced Intel SpeedStep® Technology (EIST). 1.4 System memory 1.4.1 Overview This motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Module (DIMM) sockets. A DDR2 DIMM has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket. The figure illustrates the location of the DDR2 DIMM sockets: DIMM_A1 DIMM_A2 DIMM_B1 DIMM_B2 P5QL-VM DO P5QL-VM DO 240-pin DDR2 DIMM sockets ASUS P5QL-VM DO 1-3
